1. I would choose channel 3. I would choose this option because I feel that the instructor and I would have a better conversation about it outside of class. While scheduling the meeting I would bring up why I feel like this is not acceptable, but not getting into too many details. But expand on it during our meeting so we could have more time and private conversation. Scheduling a meeting is the best choice in communication channel for this situation. It will give you time to calm down and think rationally; therefore, your verbal and nonverbal communication skills will be more assertive rather than aggressive, and they will appear more genuine/honest.
